This product is shipped in a package containing five separate plastic sachets. Open the package and remove one sachet. Slide the separator from the sachet's center to allow the components to mix. Knead the sachet for about 15 seconds thoroughly mixing the contents to a uniform consistency. Slit open the package and apply the epoxy as required. Warming any epoxy (between 50°C and 80°C) during curing, shortens the curing time and increases the final bond strength. But heating initially decreases the viscosity and you must be wary of creating drips that cause unintended seals.
